There is a built-in feature of windows to change resolution of the screen but Display Changer has got something more to do with screen resolutions. With Display Changer you can do a lot of things by changing your screen resolution parameters. It is capable of changing resolution of your own choice by specifying desired parameters which mainly includes width, height, depth, refresh rate, fixed output, rotate and by specifying position includes left,right,top and bottom.
This freeware is worth it if you don’t want to be hassled with changing the resolution of the screen after playing games or using apps which require resolution change. It happens sometimes that the resolution does not roll back to the default after the game has ended or an application closed. I reckon you create a script or batch file first and write the desire resolution parameters in it.
Open folder where you’ve installed Display Changer and include this line of code into batch file. In case you don’t know how to create a batch file, learn the basics here.
dc.exe -dccmd.exe –listmonitors
When executed, it would return the current screen resolution along with refresh rate and monitor type.
You can include this line of code to change the screen resolution with different parameters.
dc.exe -width=640 -height=480 -refresh=60 (more parameters can be added if desired)
But if you need to change the screen resolution for a specific program or a game that requires different resolution. For instance, if you want to run DVDMaker in 640×480 resolution, you will need to insert this line of code into BAT file.
dc.exe -width=640 -height=480 -refresh=60 C:\Program Files\DVD Maker\DVDMaker.exe
This batch file would execute DVDMaker in 640×480 resolution with the refresh rate of 60 and when closed, Display Changer will roll back to the original VGA setting.
In some cases if you want to run a Microsoft Office suite app with different resolution then specify the following parameters,
dc.exe -width=1280 -height=768 -refresh=60 cmd /c “C:\Program Files\data.xlsx”
The above line of code will open the spreadsheet in the specified screen resolution and restore the original VGA settings when it is closed. Some of the notable features of Display Changer can be seen on the product page.
It is compatible with both 32-bit and 64-bit OS and works brilliantly on Microsoft Windows 7, Microsoft Vista, Windows XP Home and Professional, Windows 2003 Server and Windows 2008 Server.
